Preschoolers' Attachment to Mother and Risk for Adjustment Problems in Kindergarten: Can Teachers Make a Difference?

Based on attachment theory, two aims were addressed. Firstly, we tested whether close teacher–child relationships may buffer children who are less securely attached to their mothers against negative outcomes, such as aggressive behavior. Secondly, our study evaluated whether teacher sensitivity may protect less securely attached children against forming less close relationships with their teachers. In a sample of 127 children, mother–child attachment was observed in preschool. In kindergarten, teacher sensitivity was observed, and teacher–child closeness and child aggressive behavior were rated by the teacher. Results of multilevel hierarchical regression analyses first showed that with high teacher–child closeness, less securely attached children are no longer at risk for more aggressive behavior. Secondly, it was found that with high teacher sensitivity, less securely attached children are no longer at risk for developing less close relationships with their teachers.     

民族地区乡村经济行为模式、动机体系及其变迁研究

民族地区乡村经济中的主导经济行为模式至少存在四种类型。民族地区人们的经济行为大致有三种基本的动机体系。改革开放以来,有五种主要因素在改变着这些经济动机体系和行为模式,一是乡(镇)政府、具有准政府性质的村集体组织以及其他各种组织的推动、示范和劝导作用,二是体制改革的推动或压力,三是文化移入的诱导或冲击,四是内部创新行为的出现,五是特定文化传承的激活。     

Using Panel Data to Understand the Dynamics of Human Behavior in Response to Flooding

Insights into the dynamics of human behavior in response to flooding are urgently needed for the development of effective integrated flood risk management strategies, and for integrating human behavior in flood risk modeling. However, our understanding of the dynamics of risk perceptions, attitudes, individual recovery processes, as well as adaptive (i.e., risk reducing) intention and behavior are currently limited because of the predominant use of cross-sectional surveys in the flood risk domain. Here, we present the results from one of the first panel surveys in the flood risk domain covering a relatively long period of time (i.e., four years after a damaging event), three survey waves, and a wide range of topics relevant to the role of citizens in integrated flood risk management. The panel data, consisting of 227 individuals affected by the 2013 flood in Germany, were analyzed using repeated-measures ANOVA and latent class growth analysis (LCGA) to utilize the unique temporal dimension of the data set. Results show that attitudes, such as the respondents’ perceived responsibility within flood risk management, remain fairly stable over time. Changes are observed partly for risk perceptions and mainly for individual recovery and intentions to undertake risk-reducing measures. LCGA reveal heterogeneous recovery and adaptation trajectories that need to be taken into account in policies supporting individual recovery and stimulating societal preparedness. More panel studies in the flood risk domain are needed to gain better insights into the dynamics of individual recovery, risk-reducing behavior, and associated risk and protective factors.     

共享单车用户机会主义行为的演化博弈分析

目前为止,共享单车用户的机会主义行为是共享单车能否发展的关键制约因素之一。基于此,尝试用演化博弈理论建立共享单车企业与用户间的演化博弈模型发掘用户的机会主义行为动因及利益相关者作用。研究表明:用户收益是其行为选择的决定性因素,用户机会主义行为收益大于规范行为收益是机会主义行为的产生根源;共享单车企业的激励约束可对用户行为起到调节作用,约束强度将对用户机会主义行为的程度产生负向影响。最后,针对演化博弈模型分析结果,提出了相应管理对策建议。

损失厌恶、后悔厌恶与沉没成本效应的关联性分析

以往研究认为沉没成本效应的产生与损失厌恶和后悔厌恶相关,但对其相互关系的探讨较少考虑货币性沉没成本和非货币性沉没成本的不同影响.文章选取证券监管者和证券市场投资者作为被试对象,通过有情境因素的调查问卷对损失厌恶、后悔厌恶与沉没成本效应之间的关联性进行验证.实证结果发现,与证券市场投资者相比,证券监管者的损失厌恶倾向要显著更低,而二者的后悔厌恶和沉没成本效应则无显著差异;证券监管者的数据结果表明,后悔厌恶与沉没成本效应之间存在显著的相关性,而损失厌恶与沉没成本效应之间不存在显著的相关性;相比之下,证券市场投资者的数据结果则表明,损失厌恶与沉没成本之间存在显著的相关性,而后悔厌恶与沉没成本之间则不存在显著的相关性.     

农户和农业主体对土地承包经营权抵押贷款政策的态度

一项政策的实施效果与主体看待该政策的态度密切相关。研究1基于1 002份有效问卷,引入态度的三维度模型,将农业主体对土地承包经营权抵押贷款的态度分成认知态度、情感态度与行为态度。结果显示：主体对土地产权的认知存在一定的偏差,对贷款政策的认知程度不高;对政策具有较高的满意度,认为能在一定程度上缓解资金难问题,增加农业收入;但利用政策贷款意愿度并不高。研究2基于857份农户和145份农业新型经营主体有效问卷,选用态度强度以及态度中心性,对农户与新型经营主体态度进行差异性分析。结果显示：农户与农业新型经营主体在态度强度与中心性上均存在不同程度的差异性。态度强度上,行为强度差异显著,认知强度部分显著,情感强度不显著。中心态度上,农户的中心态度是认知态度,而新型经营主体是情感态度。此外,对农户与新型经营主体贷款意愿进行关联性分析,发现影响贷款意愿的态度具有差异性。可见,农户与新型经营主体态度差异是影响贷款受益群体不均衡的原因之一。     

数字营销传播背景下的新型社会形态研究

随着数字营销传播的发展,社会形态发生了巨大的改变.数字营销传播的载体改变了传统的生活方式,让消费和传播变得更加精准,各种各样私人化的定制服务满足了人们个性化的需求.这种新型的营销传播方式让消费者在市场中占据了主导位置.数字技术在改变生活方式的同时,也改变着人们的认知系统和价值观念.经过数字营销传播的洗礼,社会结构重新部落化,沟通变得更加平等.行业之间开始融合,不同领域的行业边界变得模糊不清.以往的营销传播理念已无法满足当今大变革时代的需求,新型社会形态需要全新的营销传播理论与之相对应.

贝叶斯决策理论视域下的经济逻辑及其研究范式转向--兼析习近平经济思想

经济逻辑学是经济学和逻辑学的交叉学科,它的产生有其必然性,我们可以从经济学的基本假设、经济学的研究方法、经济学研究的确定性以及逻辑学的发展等几个角度给予论证。从贝叶斯决策理论的视角看,它是研究经济活动中理性决策和策略推理的科学。在理论驱动力和现实驱动力的双重作用下,经济逻辑的研究已开始了由形式逻辑范式向科学逻辑范式的转向。
