一类新的模式识别联想神经网络

本文提出一类可用于模式识别的联想神经网络的综合方法,这类网络结构不受对称联接的限制,网络保证了要求的M类模式的稳定形成,且网络的容量远远超过Hopfield的联想神经网络,网络渐近稳定平衡点的吸引特性使受噪声污染的模式能得以正确恢复,体现了神经网络的非线性滤波性质。文中给出了综合一个这类联想网络计算机模拟以及模式识别的例子。     

Job search monitoring intensity, unemployment exit and job entry: Quasi-experimental evidence from the UK

Because unemployment benefit reforms tend to package together changes to job search requirements, monitoring and assistance, few existing studies have been able to empirically isolate the effects of job search monitoring intensity on the behaviour of unemployment benefit claimants. This paper exploits periods where monitoring has been temporarily withdrawn during a series of Benefit Office refurbishments — with the regime otherwise unchanged — to allow such identification. During these periods of zero monitoring the hazard rates for exits from claimant unemployment and for job entry both fall.     

Reform of the UK Financial Policy Committee

We argue that: The FPC should have a wider remit; a much broader membership (covering many specialisms); should be wholly independent of Government and outside the Bank of England; its aim should be to comment publicly and authoritatively on any possible areas of risk to financial stability while itself controlling few, if any, levers of policy. The rationale for these conclusions is that: Macroprudential/financial risks come from many sources; many of these sources are structural and outside of the Bank’s regulatory purview/competence; in a sense, the Bank gets to mark its own homework as regards issues such as the SMR, resolution, appropriateness of capital, effectiveness of ring-fencing etc.; many aspects of macroprudential actions have distributional implications, and hence, politicians, not the Bank or any other body, should take and justify, or not, these decisions.     

Humor in advertising: A behavioral perspective

Humorous appeals are used extensively in television, radio, and print advertising. This article examines the effectiveness of humor in accomplishing specific communications and sales objectives. A brief review of the literature on humorous advertising research is presented. The author argues that previous unsuccessful applications of light-hearted messages are attributable, in part, to our incomplete knowledge of how consumers process humorously conveyed information. The discussion focuses on the importance of recognizing and managing variables which mediate the impact of humor on audience response and on the need for further development and testing of behavioral theory as keys to the effective utilization of humor in advertising. The author wishes to thank Dr. Phillip D. White for his helpful comments and critical review of an earlier draft of this paper.
