This paper tackles the problem of the presence of negative average rates of returns in the evaluation of the performance of mutual funds using a DEA approach. We present some extensions of DEA models for the evaluation of the performance of mutual funds that enable to compute the performance measure also in the presence of negative rates of returns. These extensions regard a model that can be u...

Neurologic complications in cancer patients commonly involve altered levels of consciousness. This chapter discusses seizures and syncope, two problems in cancer patients that can have multiple causes. Whereas normally it is easy to distinguish between these two conditions, occasionally when there are no observers of the event, it can be difficult for the clinician to be certain whether a seizu...

Results. Principal component and factor analyses identiŽed a stable Žve-factor structure accounting for 63.5% of the variance, with a primary factor of self-consciousness of appearance. Internal consistency was high (a 5 .98) and test–retest reliabilities (three months) were good (.75 (general population); .86 (patients)).Correlations with existing tests showed appropriate criterion validity (....

What is consciousness? Consciousness continues to be an illdefined concept, so I shall start by discussing how the term is used in this special issue. As discussed in Overgaard and Overgaard (2010), there is an important distinction between level of consciousness and content of consciousness. Level of consciousness refers to a dimension that varies from coma at one extreme, through sleep and, a...

Introduction Ray reported that the highly amused states of a child as well as a state of deep aesthetic appreciation are characterized by large number of pulses, and increased low frequency waves (theta and specially delta waves) (Ray, 1994). Jovanov introduced hypothetical framework of analysis for the wave patterns in theta, delta and sub-delta bands: mental consciousness for theta band, high...

The fast grow of expectations from robots and the technical obstacles the robot developers face when trying to meet the requests, force an orientation towards designing and controlling robots by following biological paragons. This tendency increases interest in human-robot analogy, and the present work is a part of this stream. The paper questions the voluntariness of human motion by relating i...

Consciousness attracts the attention of researchers representing various disciplines. Hence, there is a demand for a theoretical tool that could integrate data and theoretical concepts originating from distinct fields. The paper proposes to use the framework of the theory of integrative levels. The development and the definitions of the concept of levels are briefly discussed. The final part of...
