Bequests,gifts, and education: links between intergenerational transfers

We study the channels parents use to make transfers to their children. First, we focus on the relationship between investments in education and property transfers. Second, we turn to how property transfers are divided between inter vivos gifts and bequests. We use a Swedish dataset that is superior to previously used data as it contains information on both gifts and inheritances received from parents. We estimate models for the probabilities of having university education, receiving gifts, and receiving inheritances. In addition, we estimate models for gift and inheritance amounts. We find that the more resources parents have, the higher the likelihood of transfers, and that the correlation between receiving inter vivos gifts and inheritances is very high. Finally, women are more likely to have university education and to receive gifts, and daughters receive gifts of larger amounts than sons, although there are no differences in terms of inheritance.     

Distinction or dichotomy: Rethinking the line between thymology and praxeology

The aim of this paper is to critically reexamine Ludwig Mises’ attempt to separate the psychological aspects of understanding (thymology) from the “science of action” (praxeology). There are, we contend, legitimate distinctions between theory, on the one hand, and, on the other, psychology or history. But, there is no need to dichotomize them from one another in the way Mises sometimes did.     

Member-organization connection impacts in affinity marketing

Affinity marketing collaboration is a growing practice in the marketplace, yet theories to explain its influence are scarce in the literature. This study suggests two complementary cause-related effects stemming from an organization's connection with its members to explain the underlying mechanism of affinity marketing. The convergent findings of a survey and an experiment reveal that the responses of consumers in affinity marketing are both empathetic and particularistic. These characteristics distinguish affinity marketing from general commercial co-branding and from cause-related strategies which call for sympathetic and altruistic responses. These effects are more pronounced among individuals with a high interdependent orientation in collectivistic cultures. The dual influence of these effects makes affinity marketing an ideal marketing strategy for improving customer loyalty in the more interdependent societies in Asia.     

如何应对创新大国:中国

中国刚刚取得一项举世瞩目的具有里程碑意义的成就:它已建成世界上最快的超级计算机——天河-1A号。该计算机比设在美国田纳西州橡树岭国家实验室的卫冕冠军快40%。这不是一个孤立的事件。多年来,其他能够反映中国科技能力在不断上升的常见指标,一直在不断涌现,比如,在世界领先的化学和物理学杂志上,来自中国的论文所占的比例在不断增加。     

我国国民福祉演进轨迹及其政策效应

国民福祉可以通过经济、社会、文化、环境等客观指标加以体现。运用国民福祉评价模型对1996~2009年间我国四大区域及全国31个省级行政区国民福祉的时空演进特征进行实证分析,检视我国区域协调发展战略的政策效应,并结合以人为本的科学发展理念和构建和谐社会的目标,提出进一步协调我国区域发展的政策方向。我国在发展经济过程中,应重点关注经济增长对国民福祉的提高程度。

能源回弹效应下高碳产业低碳转型过程中的技术突变性

考虑能源回弹效应下,分析高碳产业低碳技术突变技术门槛,发现技术碳减排存在由量变到质变的门槛效应,另外还发现能源回弹对门槛效应具有显著影响。运用Hansen门限面板模型、结合CD生产函数的能源回弹模型发现：①不考虑能源回弹效应,高碳产业低碳化过程中的技术突变存在两个门槛;②考虑能源回弹作用,将减少为一个门槛,并且将延长高碳产业完成低碳技术突变所需时间。因此,为加快高碳产业低碳技术突变,有效减少碳排放,一方面应缓解能源回弹效应的影响,对能源回弹效应较大的高碳产业采取实时监控,对能源回弹较小的高碳产业采取定期检查和不定期抽检方式监控;货币政策、财政政策和产业政策相互配合,在高碳产业拉动经济增长的同时,最大限度控制能源回弹效应。另一方面,市场手段和政府职能双管齐下,协助企业低碳技术升级和设备改造,优化税收结构,弥补低碳技术升级导致的负外部性,完善高碳产业转移或市场退出机制。

一种新的混沌扩频序列产生方法

本文提出了一种新的混沌扩频序列产生方法。该方法基于神经网络的强大学习能力和副近非线性函数能力,应用具有全局最优的ＢＰ改进算法通过训练学习建立起具有混沌性态的优化神经网络模型,利用网络权值调整的灵活性来产生混沌扩频序列。计算机仿真结果表明,该模型产生的混沌扩频序列调整更容易,比基于单一混沌映射能产生更多符合扩频通信要求的扩频序列。     

酶联免疫法与液相色谱-串联质谱法测定水产中氯霉素残留

运用酶联免疫法和液相色谱-串联质谱法测定水产中的氯霉素残留。结果显示,ELISA法最低检测限为0.0125μg/kg,鱼、虾、贝类样本的添加回收率为80.4%-101.3%,变异系数为5.7%-11.5%;LC-MS/MS法最低检测限为0.1μg/kg,样本添加回收率为82.7%-98.2%,变异系数为6.2%-9.7%。用酶联免疫法对实际样品进行检测,筛选出5个阳性样本,经液相色谱-串联质谱法确证亦为阳性,且测定结果一致。研究表明,酶联免疫法快速、灵敏、可靠,为水产品中氯霉素的残留检测提供了快速筛选方法,而液相色谱-串联质谱法准确度高,适用于阳性样本的确证和精确定量。
