Motive forces of migrating pseudoplasmodia (slugs) of Dictyostelium discoideum were determined by application of a double-chamber method. The motive force of a whole slug was proportional to its volume, the value per unit volume being 5.85 x 10(-6) dyne/cm3 (58.5 N cm-3). The motive force was independent of temperature (13.5--26 degrees C) and decreased during prolonged migration. Motive force ...

This paper examines how aversion to risk and aversion to intertemporal substitution determine the strength of the precautionary saving motive in a two-period model with Selden/Kreps-Porteus preferences. For small risks, we derive a measure of the strength of the precautionary saving motive which generalizes the concept of “prudence” introduced by Kimball [12]. For large risks, we show that decr...

The neural basis of action understanding in humans remains disputed, with some research implicating the putative mirror neuron system (MNS) and some a mentalizing system (MZS) for inferring mental states. The basis for this dispute may be that action understanding is a heterogeneous construct: actions can be understood from sensory information about body movements or from language about action,...

Person-environment fit has been identified as a key prerequisite for employee well-being. We investigated to what extent a misfit between motivational needs and supplies at the workplace affects two key health outcomes: burnout and physical symptoms. Individual needs (implicit affiliation and power motives) and environment supplies (motive specific job characteristics) were assessed in an onlin...

We prove that the Chow motive of an anisotropic projective homogeneous variety of type F4 is isomorphic to the direct sum of twisted copies of a generalized Rost motive. In particular, we provide an explicit construction of a generalized Rost motive for a generically splitting variety for a symbol in K3 (k)/3. We also establish a motivic isomorphism between two anisotropic non-isomorphic projec...

participation in clinical trials can be useful for the health of a person, in who it is conducted, but it does not have to be - it can even be harmful. therefore, primary motive to accept such risk is humanity and human wish to contribute to the progress of medicine; this is expressed by personal consent. the consent, however, can be an expression of personal humanity, and for this, it is not l...

    Background: Visit length is an indicator that can be used to assess patients’ satisfaction of the health care services. In recent years, some studies have focused on the mean visit time in Iran. This study aimed at determining the average visit time in Iran by performing a systematic review and meta-analysis.    Methods: In this study, Embase, PubMed/MEDLINE,...
