In this paper, we study corporate social responsibility (CSR) in China through the prism of investments. We work with large stocks and assess their CSR performance from agency CSR data. We formulate Chinese CSR by a multiple objective extension of a traditional portfolio selection model and analytically solve the extension. We also solve the extension by a genetic algorithm and directly evaluate the algorithm's performance against the analytical solution. The multiple objective formulation is tested by randomly choosing nondominated portfolios with out‐of‐sample data to identify nondominated portfolios that outperform the 1/n portfolio (equally weighted portfolio).

Past studies indicated that people in a minority (vs. majority) position are slower to express their public/political opinion, and the larger the difference between the size of the two positions, the slower the response. Bassili termed this the minority‐slowness effect (MSE). In the current study, two experiments were conducted to demonstrate that MSE extends to people's understanding of utterances and explored the cognitive basis for this. Participants were asked to judge if an utterance is a ‘direct’ or an ‘indirect’ expression. The results show that participants in the minority (vs. majority) took longer to respond, and the larger the difference between the size of majority and minority, the longer the response latency (Study 1a). Furthermore, participants were aware of their own minority position (Study 1b). In Study 2, when participants were deprived of cognitive resources, MSE disappeared, presumably because participants lack the cognitive resources required to conform to utterance interpretation as favoured by the majority.  相似文献

Several psychophysical studies of visual short-term memory (VSTM) have shown high-fidelity storage capacity for many properties of visual stimuli. On judgments of the spatial frequency of gratings, for example, discrimination performance does not decrease significantly, even for memory intervals of up to 30 s. For other properties, such as stimulus orientation and contrast, however, such “perfect storage” behavior is not found, although the reasons for this difference remain unresolved. Here, we report two experiments in which we investigated the nature of the representation of stimulus contrast in VSTM using spatially complex, two-dimensional random-noise stimuli. We addressed whether information about contrast per se is retained during the memory interval by using a test stimulus with the same spatial structure but either the same or the opposite local contrast polarity, with respect to the comparison (i.e., remembered) stimulus. We found that discrimination thresholds got steadily worse with increasing duration of the memory interval. Furthermore, performance was better when the test and comparison stimuli had the same local contrast polarity than when they were contrast-reversed. Finally, when a noise mask was introduced during the memory interval, its disruptive effect was maximal when the spatial configuration of its constituent elements was uncorrelated with those of the comparison and test stimuli. These results suggest that VSTM for contrast is closely tied to the spatial configuration of stimuli and is not transformed into a more abstract representation.  相似文献

This qualitative study aimed to examine the inclusive practices implemented in three faith-based kindergartens in Hong Kong. A questionnaire was used to collect information about school backgrounds, students’ special needs, teacher training, special education services, curriculum design, school policy, parental involvement, and challenges faced by these schools when implementing their inclusive practices. The primary focus of this study was the influence of faiths on the provision of inclusive services for children with special needs. The results indicated that faiths, along with other factors, have played a significant role in contributing to the inclusive education services provided to children in these schools.  相似文献

为了探讨围手术期给予阿托伐他汀负荷剂量对急性ST段抬高型心肌梗死(STEMI)患者急诊经皮冠状动脉介入治疗(PCI)后对心血管事件的影响。选取因STEMI行急诊PCI术患者160例,其中80例于PCI术前给予阿托伐他汀负荷剂量40mg,80例术前未给予阿托伐他汀负荷剂量进行研究。分析两组患者住院期间肌酸激酶同工酶与超敏C反应蛋白值,PCI术后与术后1个月心功能情况。结果显示围手术期阿托伐他汀负荷剂量组主要心血管事件发生率优于非阿托伐他汀组(P〈0.05)。因此,围手术期给予负荷剂量的阿托伐他汀可以降低住院期间不良心血管事件的发生率,改善患者预后。  相似文献

为探究理性行动理论和社会认同理论两大社会心理学宏论对于个体集体行动参与倾向的共同解释力,以“中日撞船事件”为考察蓝本向天津市431名大学生被试进行调查研究,结果发现:效能和社会规范作为态度和行动倾向的中介变量,在不同情境下对行动倾向的作用不同,符合理性行动原则;内部动机作为态度和效能、社会规范之间的中介变量,并受到学校认同和国家认同的直接或间接影响,支持了社会认同理论对遵从规范行为的解释;回归分析验证了不同水平认同对行动倾向作用程度的差异,整合模型则揭示了其具体的作用路径和影响机制.结论:理性行动理论与社会认同理论可彼此互补成为集体行动参与的整合性解释框架.  相似文献

文章采用模拟研究, 分别在混合多层模型假设满足和违背的情境下, 比较了混合多层模型方法与标准化残差系列方法在识别不努力作答和参数估计方面的表现。结果显示:(1)不存在不努力作答或其严重性低时, 各方法表现接近; (2)不努力作答严重性高时, 固定参数迭代标准化残差法普遍更优, 混合多层模型法仅在假设满足且两种作答反应时差异大的条件下表现较好。建议实际应用中优先选择固定参数迭代标准化残差法。  相似文献
