明星模仿的侵权认定与例外——以形象权保护为视角

我国法学界对明星模仿涉及的法律问题给与了很多讨论,讨论的主题涉及明星模仿的方式、侵权构成要件、法律规制等方面。目前来看,理论界对于明星模仿侵犯了权利人的合法权益并无异议,但对于认定侵权的标准和侵犯了权利人何种权益等问题仍有待进一步讨论。本文试图引进形象权的概念和形象权理论中＂附带使用＂规则对明星模仿侵权相关理论进行分析。     

Bulging biceps and tender kisses: the sexualisation of fatherhood

This article explores recent developments in masculinity, focusing on the sexualisation of fatherhood in Anglophone media. As it becomes socially acceptable for men to engage with “hands-on” fatherhood roles that had previously been primarily associated with motherhood, the appeal lies not just in this shift in gendered performance, but the representation of this as an opportunity for men to reveal a desirably body image. Where previously the hands-on fatherhood role had been glossed as “nappy changing duties,” this more recent development focuses on men’s bodies and in particular the act of carrying a young child which affords the chance for biceps to be flexed in juxtaposition with the gentle act of holding a child. Colloquially, this has led to the emergence of the “DILF,” particularly on social media where sites are devoted to photos of such men.     

Semiotising the student perception of learning outcomes in British higher education

This article presents a semiotic analysis of the student perception of learning outcomes in British higher education. It centres on three annotated images in Frank Furedi’s article “The Unhappiness Principles”, published in Times Higher Education in 2012. Drawing upon Peircean semiosis and iconicity, it provides a rhetoric-infused interpretation of the word–image complementarity exhibited in student participants’ written commentaries on the three images. This leads to a dialectical view of formative and summative assessment, in which process and product create each other through the same continuum of learning and teaching. In highlighting intellectualism as central to the ethnography of university life, this article argues that learner autonomy and the potential for transformation is deemed essential to the student experience in higher education.     

“We have to tell our own story”: semiotics of resisting negative stereotypes of Nigeria in the heart of Africa nation branding campaign

This study examines the semiotic resources deployed in resisting negative stereotypes of Nigeria in the international community, particularly representations of the country in the Western media. Data for the study were drawn from Nigeria’s Heart of Africa nation branding campaign. The study applies the discourse-historical approach (DHA) pioneered by Ruth Wodak of the Vienna School of CDA. DHA attempts to integrate much available knowledge about the historical sources and the background of the social and political fields in which discursive events are embedded. Further applying Reisigl and Wodak's presentation of the discursive strategies normally oriented towards understanding texts related to nations and national identities, among others, the study reveals that in appropriating the semiotic resources in the campaign, the discourse producers have predilection for the discursive strategies of mitigating negative attributes which the out-group intensifies, and highlighting positive attributes which the out-group seemingly under-reports in its representations of Nigeria. Notwithstanding the rhetorical dynamics of the semiotic resources, the study concludes that enduring national image management thrives on creating new images and associations lived by a country’s citizens rather than tries to refute old ones.
