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 ...

Learner autonomy has been described as the ultimate objective in many language teaching programs since the third quarter of the twentieth century and educators have highlighted the significant role of promoting learner autonomy in the process of language learning and teaching. However, only limited number of studies has been awarded to what leaner autonomy mean to teachers. This study addressed...

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...

Objective: To examine the internal consistency and factor structure of the Brazilian adaptation of the UPPS Impulsive Behavior Scale. Methods: UPPS is a self-report scale composed by 40 items assessing four factors of impulsivity: (a) urgency, (b) lack of premeditation; (c) lack of perseverance; (d) sensation seeking. In the present study 384 participants (278 women and 106 men), who were recru...
