With the emergence of new technologies, in particular the Internet, the opportunity for impulsive purchases have expanded enormously. In this research-in-progress, we report the current status of an fMRI-project in which we investigated differences between neural processes in the brains of impulsive and non-impulsive shoppers during the trustworthiness evaluation of online offers. Both our beha...

Suicide attempts often are impulsive, yet little is known about the characteristics of impulsive suicide. We examined impulsive suicide attempts within a population-based, case-control study of nearly lethal suicide attempts among people 13-34 years of age. Attempts were considered impulsive if the respondent reported spending less than 5 minutes between the decision to attempt suicide and the ...

This paper presents a simple and cost effective method to remove the periodic impulsive noise in power-line communications (PLC) system. In the real PLC environment, some electrical appliances will produce impulsive noise at a fixed frequency with the power spectral density (PSD) usually exceeding that of the received signals. This type of impulsive noise is the periodic impulsive noise, and it...

Using a sample of 163 consumers, the study provided evidence that arousal and perceived risk had effects on impulsive buying behavior. Perceived risk was negatively associated with impulsive buying behavior but not significantly related to impulsive buying intention, whereas pleasure, which was not related to actual behavior, was a predictor of impulsive buying intention. On the other hand, the...

We prove several results concerning topologic conjugation of two impulsive semidynamical systems. In particular, we prove that the homeomorphism which defines the topologic conjugation takes impulsive points to impulsive points; it also preserves properties as limit sets, prolongation limit sets, the minimality of positive impulsive orbits as well as stability and invariance with respect to the...

OBJECTIVE A considerable proportion of suicide attempts are the result of sudden desires. Understanding such impulsive suicide attempts is necessary for effective interventions. We evaluated the impulsivity of suicide attempters treated in emergency rooms. The aim of the study was to identify the characteristics of impulsive suicide attempts by comparing these individuals to those who attempted...

Doncaster and Shepherd (1) reported that hatching of eggs of Heterodera rostochienis Woll. was preceded by larval movement, by purposeful and accurate stylet thrusts which cut a slit at the end of the egg shell, and by forward body thrusts of the larva which forced the slit open and allowed it to escape. We crushed in distilled water 30 cysts of H. iri Mathews found in association with creeping...

Two tectonic scenarios have been proposed for genesis and emplacement of the Oman ophiolite. One suggests that the ophiolite was generated at a spreading center, the other suggests generation within an intraoceanic arc. An integrated thermal and kinematic model of the temperature, stress, rock type, and displacement fields during early stages of the emplacement ofthe Oman ophiolite was develope...
