Previous research on cyberbullying has almost entirely focused on examining its prevalence among teens and young adults leaving it unclear how prevalent it is within the wider population. The present study used a New Zealand (NZ) national sample (N = 20,849) to examine gender, age, and ethnic differences in the experiences of cyberbullying victimization. On average, nearly 14.9 percent of respondents stated that they have ever been a target of cyberbullying before, with 2.2 percent respondents reporting such experiences within the past month. While young adults (18-25 years) experienced the highest levels of cyberbullying during both time frames (lifetime and past month), the prevalence of cyberbullying was lower among older age cohorts, with the lowest rate among the 66+ age group. Reports of cyberbullying slightly varied among men and women, with women overall reporting slightly greater levels of having ever experienced cyberbullying than men; however, this significant difference did not carry into reports of cyberbullying over the past month. On average, participants identifying as European reported lower levels of cyberbullying than M aori and Pacific Nations participants during both time frames, with Asian participants falling in the middle. Taken together, these findings provide a nuanced understanding of the prevalence of cyberbullying in a large national sample of NZ adults.

Wnt4 (Wingless-type MMTV integration site family member 4) has been demonstrated to play critical roles in a wide variety of biological processes, including embryonic development, cell proliferation, and differentiation in vertebrates, but its function in crustaceans is still not clear. In the present study, the full-length wnt4 cDNA sequence was cloned and characterized for the ridgetail white prawn Exopalaemon carinicauda. The expression patterns of the wnt4 mRNA in embryos and larvae at different stages were investigated. The tissue distribution showed that wnt4 was obviously expressed in eyestalk and hepatopancreas. During embryonic development, the wnt4 was highly expressed in all developmental stages except the zygote, two-cell stage, and late zoaea stage. The wnt4 mRNA was expressed in Z1-Z5 and post-larval stages. Taken together, the present study indicates that the wnt4 gene may be involved in the regulation of embryonic and larval development in the ridgetail white prawn.
