Retraction statements and research malpractice in economics

We draw on rational crime theory to help analyse 55 articles that have been retracted from 734 peer-reviewed journals in the field of economics. We highlight and discuss what these findings indicate regarding the nature and pattern of research malpractice in that discipline. Particular attention is given to exploring “no reason” retractions and the policy guidelines of publishers regarding retracted papers. We conclude that the frequent vagueness of retraction statements, and a reluctance to signal research malpractice, generally results in little damage to the reputation of caught, and known, offenders. Thus, a key deterrent to engaging in research malpractice is lacking. To reduce the incidence of research malpractice, we offer several recommendations for publishers and journal editors.     

Technology intensity and agglomeration economies

This article investigates the relationship between industry technology intensity and the impacts of agglomeration economies on industrial growth. Many recent studies suggest the actual economic impacts of different forms of agglomeration economies depend on industrial characteristics such as technology intensity, but systematic empirical evidence is still lacking. To fill this gap, we analyze employment data covering all 3-digit NAICS industries of U.S. counties. The results confirm that technology-intensive industries are more likely to benefit from Jacobs spillovers as measured by related variety, while sectors with low technology intensities can better benefit from MAR spillovers as measured by regional specialization.

16路抢答器电路改进设计

针对李燕等基于74LS系列数字集成电路的《多路抢答器设计》之不足,提出了16路抢答器电路的3种改进设计方案。该电路可以将最先抢答者的编号从1-16正确显示出来。采用Multisim 11软件仿真实验证明,其电路设计合理,方案可行。     

Neues zur beruflichen Anerkennung im EU-Bereich

Die berufliche Anerkennung im EU-Bereich war bisher durch ein Konvolut zahlreicher und wenig übersichtlicher Regelungen geprägt, weshalb sich eine Orientierung auf diesem Gebiet nicht gerade einfach gestaltete. Durch die neue RL 2005/36 über die Anerkennung von Berufsqualifikationen erfolgt nunmehr die bereits längst nötige Harmonisierung. Der folgende Beitrag bietet eine Übersicht zur beruflichen Anerkennung, wobei insbesondere die wichtigsten Inhalte der neuen RL – vom Anerkennungssystem bis zu den Kontaktstellen – zur Darstellung gelangen.

第十一届全运会田径项目综合实力分析

运用文献资料法、数理统计法、比较分析法和逻辑归纳法,以第10届、第11届全运会奖牌和积分为研究对象,并进行分析,结果表明：①从世界范围来看,我国田径项目接近世界水平比较少,女子项目优于男性项目,在进入世界水平的项目中,主要集中在耐力和快速力量项群上。②全运会田径奖牌分布相对分散,各省市综合实力重新洗牌。③按照项群理论进行分析：速度项群中鲁、苏、粤实力显著;耐力性项群中鲁、苏、黑优势明显;快速力量项群中冀、鲁并驾齐驱;综合项群中辽独领风骚。

Knowledge coherence, variety and economic growth: Manufacturing evidence from Italian regions

This paper elaborates a view on knowledge as a result of a combinatorial search activity, so as to investigate its effects on economic growth at the regional level. Empirical estimations corroborate the hypothesis that knowledge coherence and variety, besides the traditional measure of knowledge stock, matter in shaping regional economic performances. The check for spatial dependence suggests that cross-regional externalities exert additional triggering effects on growth, without debasing the effects of knowledge properties. Important policy implications stem from the analysis, in that regional innovation strategies should be carefully coordinated so as to reach a higher degree of internal coherence and trigger economic performances.
