Adolescents’ Social Network Site Use,Peer Appearance-Related Feedback,and Body Dissatisfaction: Testing a Mediation Model

Previous correlational research indicates that adolescent girls who use social network sites more frequently are more dissatisfied with their bodies. However, we know little about the causal direction of this relationship, the mechanisms underlying this relationship, and whether this relationship also occurs among boys to the same extent. The present two-wave panel study (18 month time lag) among 604 Dutch adolescents (aged 11–18; 50.7 % female; 97.7 % native Dutch) aimed to fill these gaps in knowledge. Structural equation modeling showed that social network site use predicted increased body dissatisfaction and increased peer influence on body image in the form of receiving peer appearance-related feedback. Peer appearance-related feedback did not predict body dissatisfaction and thus did not mediate the effect of social network site use on body dissatisfaction. Gender did not moderate the findings. Hence, social network sites can play an adverse role in the body image of both adolescent boys and girls.     

Equilibria in multi-party systems

This paper deals with equilibria in multi-party systems, not excluding systems with two parties. The model has a one-dimensional policy space for the positions of parties and voters. Furthermore it assumes an arbitrary continuous density of voters, voters vote for the nearest party, and parties try to maximize the number of votes. Sufficient and necessary conditions for equilibria are given, and from these conditions it is deduced that for systems with a large number of parties equilibria are rare, unless the density of voters is uniform.     

Simbole in interkulturele kommunikasie

SUMMARY

The first part of this article: “Symbols as message-bearers” discusses the nature and occurrence of symbols, symbol systems and classifications, and the way these manifest a society's specific world view. Symbolic systems are paradigms in which certain concrete cultural constructions (eg. houses, meals, clothes etc.) occur as syntagms. The analysis of symbolic mechanisms grants access to a culture's unique constitution of meaning. Verbal and non-verbal communication symbols are briefly discussed.

The second part depicts the manifestation of symbols in certain cultural arrangements in which symbolization plays a great part, like myths, religion, art and rituals.

The final part maintains the use of symbol analysis as utilization of the cultural totality for intercultural communication. By involving the symbol system as well as the unique communication patterns, successful communication transcending intercultural boundaries, becomes more likely.
