Aggressive behaviors negatively impact peer relations starting from an early age. However, not all aggressive acts have the same underlying motivations. Reactive aggression arises as a response to an antecedent behavior of someone else, whereas proactive aggression is initiated by the aggressor and is instrumental. In this study, we aim to understand the relation between reactive and proactive aggression and peer acceptance in preschoolers. Parents of 110 children aged between 3 and 6 years old rated their children’s manifestation of reactive and proactive aggressive behaviors. To assess the c

The role of self-regulation in aggression has typically been studied by neglecting the multidimensional nature of aggression, which differentiates between its forms (overt vs. relational) and functions (proactive vs. reactive). Besides, the contribution of two aspects of self-regulation (effortful control and reactive control) in the regulation of aggression has been ignored. Studies suggest that only reactive aggressive children have low effortful control because aggression results from the insufficient inhibition of an aggressive impulse. On the other hand, some studies suggest that proactiv

Hostile attribution bias (HAB), the tendency to perceive hostility in ambiguous situations, has been linked to aggressive outcomes, such as reactive aggression. HAB has been connected to personality types involving hostile beliefs and reactive aggression, including narcissism and psychopathy. Specifically, secondary psychopathy is associated with HAB and reactive aggression. Despite research and theory connecting these constructs, few studies have examined if HAB mediates the relationships among psychopathy, narcissism, and aggression.

Traditional masculinity includes norms that encourage many of the aggressive behaviors whereas traditional femininity emphasizes aggression very little. In addition, the lack of emotional regulation as well as a poor impulse control have been related to aggression and, in particular, with reactive and proactive aggression.

Abstract. Negative urgency defined as the tendency to act rashly when faced with intense negative emotions and hostile attribution bias (HAB) which refers to the tendency to interpret the intention of others as hostile when social context cues are ambiguous are two key psychological factors underlying reactive aggression. However, the specific associations between these factors in relation to reactive aggression have not been tested yet with competing models.

Recent efforts to understand and predict the onset and maintenance of aggression have considered the heterogeneity of this behavior. Dodge (1980) and others, have suggested a distinction in aggression based on two primary subtypes: reactive and proactive aggression. The form, severity and persistence of these aggressive subtypes may depend on an on-going interaction between individual characteristics and environmental characteristics that elicit varying antecedents and consequences (Frick, 1998; Lahey et al., 1999).

Violence is a devastating social phenomenon that is costly both to affected individuals and to society at large. Pathological aggression, especially reactive/impulsive aggression, is a cardinal symptom common to several psychiatric disorders—including antisocial personality disorder, borderline personality disorder, and psychopathy—that are associated with risk for violence. Thus, understanding the factors that predispose people to impulsive violence represents a crucial goal for psychology, neuroscience, and psychiatry.

The reaction of the alkali chloride with the oxide scale on metals releases chlorine which causes accelerated corrosion. The corrosion rate can be reduced

Abstract The corrosion behaviour of magnesium alloys is not substantially comparable to other light metal alloys, it is more similar to that of steels. Voluminous reaction products, formed in neutral electrolytes, leads to a diffusion controlled dissolution on the surface of the underlying magnesium alloy. Therefore, influences from structure and alloying are suppressed very strongly. In alkaline environments, passivation occurs as a result of the formation of a hydroxide layer on the magnesium surface. Therefore, differences in the corrosion behaviour between the alloys are hardly detectable.

Abstract DNA was extracted from a water sample taken from an offshore seawater injection system. DNA was also extracted from enrichment cultures from the same sample. The V3 hypervariable region of the 16S rDNA gene was amplified by the Polymerase Chain Reaction (PCR) and bacterial diversity was studied using Denaturing Gel Gradient Electrophoresis (DGGE). The obtained results showed that microbial evaluation was biased by the use of artificial culture media although recommended media were used, indicating that microbiological analysis of waters in industrial systems by culturing methods may n

Abstract Polyvinylidene fluoride (PVDF) based polymer resins have been used for corrosive and chemically aggressive fluid containment since 1964. Original components supplied with this resin were rigid piping, valves & fittings, tanks, linings, and heat shrinkable tubing. As plastic processing technologies grew, additional products were offered such as nozzles, dump tower packing, pumps, flow meters, coatings, filtration membranes, and fabrics. In the 1980’s copolymers of vinylidene fluoride and hexafluoropropylene (HFP) were introduced to compliment the very rigid PVDF product line with a

The capability of cancer cells to resist to anoikis, migrate and invade surrounding tissues is associated with high metastatic potential and advanced stage of cancers. Recently, caveolin-1 (Cav-1) protein has garnered increased attention in implicating the aggressive behavior of cancer cells. We demonstrate herein that nitric oxide and hydrogen peroxide play a role in inhibiting anoikis process of lung cancer cells via caveolin-1 dependent mechanism. The Cav-1 function in inhibition of anoikis was demonstrated to be cause through Mcl-1 dependent mechanism. The present study demonstrated that C

Sclerotinia sclerotiorum is a filamentous fungus (mold) that causes plant disease. It has an extremely wide range of hosts (>400 species) and causes considerable damage (annual multimillion dollar losses) in economically important crops. It has proven difficult to control (culturally or chemically) and host resistance to this fungus has generally been inadequate. It is believed that this fungus occurs in almost every country. Virulence of this aggressive pathogen is bolstered by a wide array of plant cell wall degrading enzymes and various compounds (secondary metabolites) produced by the f
