The explanatory power of these perceptions on behavioral consequences as types of parental mediation is analyzed with control for previously known factors. Data from a cross-sectional population survey in Sweden 2011 covered a representative sample of children, aged 2-17 years in total 1461. The results show that the parental second-person perceptions explain （i.e., general belief in media effects） more than parental third-person perceptions. Parental second-person perceptions together with the age of the child explain most of the restrictive mediation and the effects of parental second-person perceptions on restrictive mediation increase with the parents lesser control of the media type.展开更多

Intrapreneurship can be developed in small and medium-sized enterprises where entrepreneurs have a sufficient level of creativity and it can influence the growth of enterprises. Hypotheses are specified and empirically tested based on responses to a structured questionnaire on a sample of small and medium-sized enterprises from China. The research results indicate positive relationships between the creativity of the entrepreneur and intrapreneurship and growth of the enterprise.展开更多

It is proved that the image of a （1 ＋ u）-constacyclic code of length n over F2 ＋ uF2 ＋ vF2 ＋uvF2 under a Gray map is a distance invariant binary quasi-cyclic code of index 2 and length 4n. A set of generators of such constacyclic codes for an arbitrary length is determined, Some optimal binary codes are obtained directly from （1 ＋ u）-constacyclic codes over F2 ＋ uF2 ＋ vF2 ＋ uvF2.展开更多
