Some rare and new caddis flies recorded for the Netherlands (Trichoptera)

Contains fulltext : 35412.pdf (publisher's version ) (Open Access)Since Higler published his list of extinct and endangered caddis flies species in 1995 a number of new and rare species were recorded for the Netherlands. These new findings can be partly attributed to the growing interest among researchers to study caddis flies, which has resulted in a more thorough investigation of certain water types. Other records of rare species were discovered by collecting and identifying pupae and adults, such as Hydroptila vectis and Oxyethira falcata. Some rare species, which have not been recorded since 1950, are common nowadays, possibly caused by the improved water quality of the river systems in the Netherlands. Other new species to the Dutch fauna are the result of new taxonomic insights

What other's disappointment may do to selfish people: Emotion and social value orientation in a negotiation context

The authors examined whether individual differences in social value orientation moderate responses to other’s expressions of disappointment in negotiation. The literature suggested competing hypotheses: First, prosocials are more responsive to other’s disappointment because they have a greater concern for other; second, proselfs are more responsive because they see other’s disappointment as a threat to their own outcomes. Results of a computer-mediated negotiation in which a simulated opponent expressed disappointment, no emotion, or anger supported the second prediction: Proselfs conceded more to a disappointed opponent than to a neutral or angry one, whereas prosocials were unaffected by the other’s emotion. This effect was mediated by participants’ motivation to satisfy the other’s needs, which disappointment triggered more strongly in proselfs than in prosocials. Implications for theorizing on emotion, social value orientation, and negotiation are discussed
