Prior work has shown that popular peers can set a powerful norm for the valence and salience of aggression in adolescent classrooms, which enhances aggressive friendship processes (selection, maintenance, influence). It is unknown, however, whether popular peers also set a norm for prosocial behavior that can buffer against aggressive friendship...

Although there are theoretical reasons to expect an association between ethnic minority status and popularity, research on this topic is scarce. Therefore, this association was investigated including the moderating role of the ethnic classroom composition and the mediating role of aggression. Data from the longitudinal Dutch SNARE (Social...

Previous work has shown that during adolescence, classrooms vary greatly in the extent to which aggression is rewarded with popularity (the 'popularity norm'). Aggressive popularity norms may promote the proliferation of aggression and negatively affect the classroom climate. It is, however, unknown how these norms emerge in the first place....

Anger and aggression are frequent problems in deployed military personnel. A lowered threshold of perceiving and responding to threat can trigger impulsive aggression. This can be indicated by an exaggerated startle response. Fifty-two veterans with anger and aggression problems (Anger group) and 50 control veterans were tested using a startle...

Embodied conversational agents (ECAs) have been put forward as a promising means for the training of social skills. The traditional approach to drive the behaviour of ECAs during human-agent dialogues is to use conversation trees. Although this approach is easy to use and very transparent, an important limitation of conversation trees is that...

The focus of this paper is finding a method to predict aggression using a multimodal system, given multiple unimodal features. The mechanism underlying multimodal sensor fusion is complex and not completely clear. We try to understand the process of fusion and make it more transparent. As a case study we use a database with audio-visual...

By analyzing a multimodal (audio-visual) database with aggressive incidents in trains, we have observed that there are no trivial fusion algorithms to successfully predict multimodal aggression based on unimodal sensor inputs. We proposed a fusion framework that contains a set of intermediate level variables (meta-features) between the low level...

We propose a new method for audio-visual sensor fusion and apply it to automatic aggression detection. While a variety of definitions of aggression exist, in this paper we see it as any kind of behavior that has a disturbing effect on others. We have collected multi- and unimodal assessments by humans, who have given aggression scores on a 3...

In many countries, aggression and violence at work are an increasing problem . Public services, like police, ambulances, hospitals, fire brigade, and civil services, seem to be confronted with relatively many of the incidents. Employees suffer from verbal abuse, discrimination, sexual harassment, intimidation and threatening, or even physical...

Cathodic protection delivers corrosion protection in concrete structures exposed to aggressive environments, e.g. in de-icing salt and marine climates. Working lives of a large number of CP systems are at least more than 13 years and probably more than 25 years, provided a minimum level of maintenance is applied. This involves routine checks of...

This study examined the relationship between diet-related parenting practices, parental characteristics, child characteristics, and 2-year-old child's dietary intake. Cross-sectional data (N = 2578) originated from the KOALA Birth Cohort Study. Principal component analyses revealed two restrictive parenting practice clusters: a cluster...

We have performed a long term comparative study between five wrought and three centricast materials, both as-is, and in coated condition. Two commercially available coatings were applied to each different alloy. One coating was aluminum based with a chromium rich intermediate layer. The other coating was nickel rich with substantial amounts of...

Agressie en geweld verpesten de werksfeer, schaden het imago en leiden tot verzuim. Wegwerkers vormen een regelrechte risicogroep. Zij krijgen regelmatig het gram van gefrustreerde automobilisten over zich heen. TNO onderzocht de ernst van de zaak en formuleerde maatregelen. Binnenkort komt ook de arbeidsinspectie met een rapport van controles...

The degradation mechanism metal dusting occurs in low and high pressure syngas environments between 500 and 700 C. Metal dusting is a combination of both oxidation and carburization effects, in which a (ferritic or austenitic) alloy matrix is supersaturated with interstitial carbon, usually originating from gaseous carbon monoxide. At...

OBJECTIVES. A number of studies have shown that victimization from bullying behavior is associated with substantial adverse effects on physical and psychological health, but it is unclear which comes first, the victimization or the health-related symptoms. In our present study, we investigated whether victimization precedes psychosomatic and...
