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...

1. Agents called ‘‘antidepressants’’ also treat multiple anxiety disorders such as generalized anxiety disorder, posttraumatic stress disorder, panic disorder, and social anxiety disorder; impulsive/compulsive spectrum disorders, such as obsessive compulsive disorder; eating disorders, such as bulimia; and pain conditions, such as neuropathic pain. Agents called ‘‘antipsychotics’’ are also prov...

BACKGROUND Traumatic exposure may modulate the expression of impulsive behavioral dispositions and change the implementation of emotion regulation strategies associated with depressive mood. Past studies resulted in only limited comprehension of these relationships, especially because they failed to consider impulsivity as a multifactorial construct. OBJECTIVE Based on Whiteside and Lynam's m...

The present study examines the relationship among inattentive, and hyperactive-impulsive behavior, aggression, and depression in elementary school and junior high school students. The participants were 3,885 children and their teachers and caregivers. Children's inattentive and hyperactive-impulsive behavior was rated by their teachers and caregivers (ADHD-RS). Children rated aggression (HAQ-C)...

Timely and effective feature extraction is the key for fault diagnosis of rolling element bearing (REB). However, will become very difficult in early weak stage REB due to interference strong background noise. To solve above difficulty, a two-stage method proposed, which mainly combines mode decomposition (FMD) with blind deconvolution (BD) method. Firstly, based on impulsiveness cyclostationar...

It is well known that some of urban man-made noises can be characterized by a wideband impulsive noise (pure impulsive noise). The presence of this pure impulsive noise may significantly degrade the wireless digital transmission performance. As the data rate becomes higher and the radio bandwidth becomes wider, the performance degradation due to pure impulsive interference may become larger. In...

Impulsive buying makes billions of dollars for retail businesses every year, particularly in an era of thriving e-commerce. Narcissism, characterized by impulsivity and materialism, may serve as a potential antecedent to impulsive buying. To test this hypothesis, two studies examined the relationship between narcissism and impulsive buying. In Study 1, we surveyed an online sample and found tha...

There is evidence to suggest that impulsivity is predicted by socioeconomic background, with people from more deprived backgrounds tending to be more impulsive, and by current mood, with poorer mood associated with greater impulsivity. However, impulsivity is not a unitary construct, and previous research in this area has focused on measures of 'waiting' impulsivity rather than behavioural disi...

OBJECTIVE The implications of impulsivity in its relationship with binge-eating or purging behaviors remain unclear. This study examined the patterns of eating behaviors and co-morbid impulsive behaviors in individuals with bulimia nervosa n optimally homogeneous classes using latent class analysis (LCA). METHODS All participants (n=180) were asked to complete a series of self-reported invent...

In this paper we develop Lyapunov and invariant set stability theorems for non-linear impulsive dynamical systems. Furthermore, we generalize dissipativity theory to non-linear dynamical systems with impulsive e€ ects. Speci®cally, the classical concepts of system storage functions and supply rates are extended to impulsive dynamical systems providing a generalized hybrid system energy interpre...
