系统科学视野中的制度改革与结构调整

系统科学揭示了作为复杂事物存在形式的系统的基本特征,这就是复杂性、有机性、功能自主性和自组织性。环境之间的物质、信息和能量交流与交换是系统演化与扩张的基本条件,而完成这种演化与扩张的根据则是系统内部结构与秩序的合理化。作为系统中最复杂的类型,社会系统完全服从系统的结构-功能关系原理,制度是社会系统区别于其他系统的重要特征,制度既区别于又密切相关于秩序和结构。改革就是通过制度的合理化调整,经由人的行动最终造成社会结构的合理化。这既是中国改革开放的经验总结,也是进一步深化改革的科学根据。

行为金融理论的发展与前景探析

文章首先指出行为金融理论与传统金融理论争论的核心是有效市场假说,并用行为金融理论合理地解释了传统金融理论无法解释的异象。行为金融理论认为,市场并不是完全有效的,人也不是完全理性的,投资者的决策行为受到心理因素的影响。文章介绍了行为金融理论下投资者的决策心理特征、投资决策中存在的各种偏好、及由此造成的行为认知偏差。行为金融研究投资策略的目标就是要有效的利用这些偏差来获得超额利润。

The Changing Faces of Europeanisation: How Did the European Union Influence Corruption in Slovakia Before and After Accession?

The paper looks at the European Union's impact on corruption in Slovakia, both before and after the country's accession to the European Union. It shows that even though pre-accession channels of influence diminish or disappear, membership brings new means of influence. Our methodology looks beyond institutional changes and explicit anti-corruption mechanisms. Before 1999, the European Union's influence on corruption was close to zero, and between 1999 and 2004, its influence was strong and positive. Post-accession developments are more ambiguous, but despite an apparent worsening of corruption after 2004, we observe a transformation rather than a loss of European Union influence.     

A Biopsychosocial Model of Body Image Concerns and Disordered Eating in Early Adolescent Girls

Body image and eating concerns are prevalent among early adolescent girls, and associated with biological, psychological and sociocultural risk factors. To date, explorations of biopsychosocial models of body image concerns and disordered eating in early adolescent girls are lacking. A sample of 488 early adolescent girls, mean age = 12.35 years (SD = 0.53), completed a questionnaire assessing depressive symptoms, self-esteem, body mass index (BMI), sociocultural appearance pressures, thin-ideal internalization, appearance comparison, body image concerns and disordered eating. Structural equation modelling was conducted to test a hypothetical model in which internalization and comparison were mediators of the effect of both negative affect and sociocultural influences on body image concerns and disordered eating. In addition, the model proposed that BMI would impact body image concerns. Although the initial model was a poor fit to the data, the fit was improved after the addition of a direct pathway between negative affect and bulimic symptoms. The final model explained a large to moderate proportion of the variance in body image and eating concerns. This study supports the role of negative affect in biopsychosocial models of the development of body image concerns and disordered eating in early adolescent girls. Interventions including strategies to address negative affect as well as sociocultural appearance pressures may help decrease the risk for body image concerns and disordered eating among this age group.
